Abstract:

A land snail survey was conducted on the Lucile Caves ACEC and vicinity in 1993–1994 as part of a larger survey of the lower Salmon River valley land snail fauna (Frest & Johannes, 1995). Information gathered from earlier collections in 1989–1993 was also included. The area was known to include at least one population, possibly discovered in the 1860s, of the federal candidate species Oreohelix idahoensis idahoensis (Newcomb, 1866). The authors collected at a total of 16 sites, 12 of which were wholly or mostly on the Lucile Caves ACEC. There are at least 8 land snail species in this vicinity, including colonies of three taxa regarded as sensitive by Frest & Johannes (1995a). One of these, Oreohelix idahoensis idahoensis, was historically generally distributed over much of the Lucile Caves ACEC. It now appears to be much reduced in numbers or extirpated in most places, with large populations limited mostly to small areas in the western and southwestern portions of the ACED. Cryptomastix n. sp. 5 is found only in a small seepy area below Lucile Cave. Oreohelix n. sp. 20 occurs in nearby Sheep Gulch and may be found in scattered areas at high elevations on or just east of the ACEC. Ecology of sensitive species on the ACEC is described, and recommendations for their management are made. The great single human impact in this area stems from grazing of domestic animals.
